About CR Coils

CR Coils have been made by treating hot rolled steel that is heated above recrystalization temperature in cold reduction mills to impart better characteristics. These coils are required for manufacturing numerous structures including pipes, roof sheets, and sockets. They are highly appreciated for having uniform thickness throughout roll with impact & corrosion resistance. CR Coils offered by us are available in various thicknesses and widths as required by our clients.

Features:

Assures easy formability
Good tensile strength
UV resistant nature

FAQs of CR Coils:

Q: How are CR Coils with widths of 600 mm to 1500 mm manufactured?

A: These CR Coils are produced using a cold rolling process, which involves passing mild steel through rollers at room temperature. This technique ensures precise thicknesses from 0.12 mm to 2.5 mm, superior surface quality, and enhanced dimensional consistency, matching ASTM, JIS, DIN, and EN standards.

Q: What benefits do annealed and skin-passed delivery conditions provide for CR Coils?

A: Annealed coils offer improved ductility and workability, making them ideal for applications requiring further forming, while skin-passed coils have a slightly improved surface finish and flatness. Both conditions enhance usability across fabrication, construction, and automotive industries.

Q: When should mill edge versus slit edge coils be selected?

A: Mill edge coils, with naturally rolled edges, suit general applications where precise edge tolerance isnt critical. Slit edge coils are trimmed post-rolling for tighter width tolerances and a cleaner finish, recommended for applications where exact dimensions and improved aesthetics are necessary.

Q: Where are CR Coils commonly used and why?

A: CR Coils are extensively used in the industrial, construction, and automotive sectors due to their excellent strength (yield strength 210 MPa; tensile strength 270 MPa), high-quality surface finishes (smooth, matte, bright), and adaptability to different fabrication needs. Their galvanized surface treatment ensures durability and corrosion resistance.

Q: What processes and treatments are applied to ensure CR Coil quality and performance?

A: The coils undergo cold rolling for dimensional precision, followed by surface treatments like galvanization for corrosion protection. Quality is maintained through standard export packaging, detailed inspection, and adherence to international standards, ensuring product integrity during storage and shipment.

Q: How should CR Coils be stored and handled for optimal results?

A: CR Coils should be kept in dry, covered environments and handled using proper equipment to avoid surface scratches or deformation. Correct storage and careful handling ensure the longevity and performance of the coils finish and mechanical properties for end-use applications.
